Are you attempting to run the agent on a machine *without* the ups comm connected to it, such that it will receive status from the server that does have it connected and shutdown when that remote agent that *is* monitoring the ups suggests it should?

It talks to itself over the loopback adapter. >My APC is recognized as: >APC Back-UPS 450 FW:844.Kld.D USB FW:Kld >This from the hardware browser. >PS says: >root 2419 0.0 0.0 4196 584 ?
